SPECIFICATION forming part of Letters Patent No. 365,532, dated June 28, 1887.

Application filed March 10,1887. Serial No. 230,449.

To a/ZZ whom t `'may concern:

Be it k nown that I, EDGAR GoNisroN MILLs, a subject ofthe Queen of England, residing at Manchester, in the county of Lancasten'Eugland, mechanical engineer, have invented certain new and useful Improvements in Machines for Marking Courts or Lines for Lawn-Tennis or other Purposes, of which the following is a specification.

In the front wall of a boX or cistern which contains the uid or mixture used for marking I form a slot slightly wider than the desired width of the line. A wheel with smooth nat unbroken sides,'made of wood or'a suitable hard composition or of rustless metal, is mounted in bearings outside` but near to the slotted front wall of the box, anda considerable portion of the wheel projects into the box through the slot. The. wheel runs on the ground, and is'of such asize that the bottom of the box is kept off the ground,while the top of the wheel is a little above the level of the tluid in the box when it is as full as is required.

On the accompanying sheet of drawings, Fig. Iis a sectional elevation of the machine. Fig. II is an end elevation, partly in section. Fig. III is a plan. Fig. IV shows the form in which the rubber sheet is cut, as will hereinafter be d outside the'box.

described.

In all the views similar letters of reference refer to the same parts.

a is the tank or cistern, with anv opening or slot, b, in its front wall.

Ihe wheel or disk c is mounted in bearings The level ofv the fluid in the tank, when as full as is required, is indicated by the dotted lines, as isjalso the direction of motion'of the tank and wheel by arrows.

e e are the handles by which the machine is manipulated.

In order to make good the joints up the two sides of the wheel c and at the point of its periphery where it enters the tank at f, and also in order to remove or scrape the Huid from the upper portion of the two sides of thev wheel, wherein revolvingit moves outward, I

i usea U -shaped piece of rubber, insertion, or

other suitable exible and elastic material. This is shown atg in Figs. I, III; and Fig. VIV

shows it as cut from the sheet and before being applied to vthe machine; It is mounted upon inclined pieces k, along the inside edges of the slot b, and a corresponding piece, i, on the under side.V It is thus held, as shown in the drawings, with its inner edges resting against the sides and lower periphery of the wheel in a slanting direction toward the inside of the tank. The pressure of thelinid therein tends to press the material g against the wheel.

rlwo other small wheels, k, are used to carry the hinder part of the tank, and when it is required to move the machine without marking it is tilted back and run entirely on these wheels. To prevent soil, grass, or other dirt from getting into the machine,I provide a small scraper, Z, fixed between the point of contact of the wheel with .the ground and the point where it re-enters the tank.

An iron cover, m, or any other suitable cover may be used; but such-cover forms no part of my present invention.

The action will be readilyvunderstood. The machine being propelled forward in the direction of the straight arrow the front wheel revolves, as shown by its arrow. All the fluid adhering to the periphery of the wheel is carried forward out of the tank and deposited at once on the ground, while no leakage at any away to admit the marking-wheel, and a U- shaped elastic scraper secured tothe tank, said scraper bearing on all faces of the wheel below the surface ofthe marking substance, of a marking-wheel extending into said tank'and engaging said scraper, substantially as described.
